IMPROVEMENT IN LAZY-BACKS FOR VEHICLE-SEATS.

Specification forming part of Letters Patent No. 196,377, dated October23, 1877; application filed June 27, 1877.

To all whom it may concern Be it known that I, JOHN J. NEWsoM, of thecity and county of San Francisco, and State of California, have inventedan Improved Spring Lazy-Back for Vehicles and I do hereby declare thefollowing to be a full, clear, and exact description thereof, referencebeing had to the accompanying drawings.

My invention relates to an improved arrangement for obtaining a yieldingor elastic motion in'the lazy-back of a carriage or other vehicle seat.

Referring to the accompanying drawings, Figure 1 is a perspective viewof my invention, and Fig. 2 a partial section.

Let Arepresent a seat such as is used in vehicles. B is the support forthe back of the person who sits upon the seat A, and is commonly knownas the lazy-back. Ordinarily, this back or support is rigidly secured tothe back proper of the seat by standards, and the elbows are similarlyattached.

My invention consists in supporting the rail or lazy-back 13 upon hingedstandards, and then connecting the elbow at each end to the standards,so as to allow the loose or free motion, while the front end of each armis mounted on a coiled spring, as follows:

The front end of each arm or elbow rest C is formed into or has attachedto it a coiled spring, (I. The inside end of this spring is attached toa standard, 6, which projects upward from the fixed arm F, near itsfront end. The

in a perfectly natural position, so that they act easily when a pull orstrain comes upon them.

I am aware that lazy-backs have been sup-.

ported by spring arm-rails rigidly attached, in combination withsupporting springs; but such is not my invention, the essential featureof my invention being the hinging of the lazyback, so as to allow itfull play on the spring arm-rails.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

The combination, with a lazy-back for carriage-seats, supported byhinged standards F, of the arm-rails C, hinged to the standards F, eachof said rails C being provided with a coiled spring, d, at its forwardend, attached to an upright arm, 6 F, whereby a perfectly free action ofthe springs is obtained, as specified.

In witness whereof I have hereunto set my hand and seal.
